Hydraulic back to the column back to the column 5T back to the column
The hydraulic return column is suitable for the application of the coal mining face to withdraw the supporting equipment, and is more suitable for the working face of the single hydraulic prop. The use of the hydraulic return column can greatly reduce the labor intensity of the workers, save the time of returning to the column, and improve the efficiency of the column returning. Moreover, since the column can be operated when the column is returned, the safety can be greatly improved. The hydraulic return column requires an external hydraulic source; it is mainly composed of a hydraulic cylinder, a reversing valve and a traction chain.
